Riding the Grimsel Pass

Grimsel is one of those climbs that reveals its character gradually. The lower valley feels inviting, then the road rises into a much wilder landscape of rock, water and open sky.

I find the changing scenery as memorable as the gradient. Every bend offers another reason to look up from the computer and take in the mountain around me.

History and local context

The Grimsel route runs through a landscape shaped by hydropower: giant reservoirs and dams form some of its most recognisable views.

Before you ride

The northern ascent is substantial. Food, changing weather and a long descent deserve as much thought as the climbing.
